SONAMET is the world leader in the fabrication of Riser Towers. A number of reasons account for this: firstly the concept, which was proposed for TOTAL’s Girassol development is now field proven, with no production breakdown relating to the Riser Towers’ concept. Secondly, the two projects that have opted for Riser Towers are both In Angola deep water blocks, with BP Greater Plutonio having followed into Girassol’s steps.




Thirdly SONAMET’s benchmarking achievements on Girassol, paved the way for the new Greater Plutonio Tower. Finally, the Riser Tower, in addition to its proven reliability, also features great fabrication feasibility, thus ensuring valuable transfer of technology to the host country in terms of skills and competencies and sustainable development of skilled employment.


The fabrication of Riser Towers by SONAMET is an inspiring industry model, which deserves further interest. The SONAMET yard encourages actors in the industry to pay a visit and take the measure of these unique fabrication facilities.
